/**
 * @title Ascendant Token Contract
 * @author Decentra
 * @notice Implementation of a hyper-deflationary token with Uniswap V3 integration and DragonX ecosystem rewards
 * @dev Contract inherits ERC20Burnable for token burns and Ownable2Step for secure ownership management
 *      Integrates with:
 *      - Uniswap V3 for primary liquidity pool (DragonX/Ascendant pair)
 *      - AscendantAuction for daily token distributions
 *      - AscendantPride for post-day-10 auction mechanics
 *      - AscendantBuyAndBurn for deflationary mechanisms
 *      Features:
 *      - Fixed max supply of 1.155B tokens
 *      - Initial liquidity of 5M tokens
 *      - Daily auctions for first 10 days
 *      - Automated buy-and-burn mechanism
 *      - DragonX ecosystem rewards distribution

 * @notice Adapted Uniswap V3 OracleLibrary computation to be compliant with Solidity 0.8.x and later.
 *
 * Documentation for Auditors:
 *
 * Solidity Version: Updated the Solidity version pragma to ^0.8.0. This change ensures compatibility
 * with Solidity version 0.8.x.
 *
 * Safe Arithmetic Operations: Solidity 0.8.x automatically checks for arithmetic overflows/underflows.
 * Therefore, the code no longer needs to use SafeMath library (or similar) for basic arithmetic operations.
 * This change simplifies the code and reduces the potential for errors related to manual overflow/underflow checking.
 *
 * Overflow/Underflow: With the introduction of automatic overflow/underflow checks in Solidity 0.8.x, the code is inherently
 * safer and less prone to certain types of arithmetic errors.
 *
 * Removal of SafeMath Library: Since Solidity 0.8.x handles arithmetic operations safely, the use of SafeMath library
 * is omitted in this update.
 *
 * Git-style diff for the `consult` function:
 *
 * ```diff
 * function consult(address pool, uint32 secondsAgo)
 *     internal
 *     view
 *     returns (int24 arithmeticMeanTick, uint128 harmonicMeanLiquidity)
 * {
 *     require(secondsAgo != 0, 'BP');
